CHARLES W. WALTON, OF SAN FRANCISCO, CALIFORNIA.

HYDROCARBON-FUEL BURNER.

Application filed December 19, 1917.

T0 all whom t may concern.'

Be it known that I, CHARLES W. WAL- ToN, a citizen of the United States of America, residing at the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Hydrocarbon-Fuel Burners; and I do declare the following to be a clear, full, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in liquid fuel burners wherein the liquid is converted within the burner into gas prior to its consumption and especially one wherein hydrocarbon fuels are used.

The object of the invention is primarily to produce a burner of the type set forth wherein the fuel will be super-heated prior to being gasied. When so gasied, this will be done to such a superlative degree as to eliminate carbon and soot resulting from combustion, and such combustion will result in a pure, clean, blue flame as is highly desirable in this type of burner.

A further object of the invention is to provide a double burner having a common source of the liquid fuel supply, but each having an independent control of its gas outlet whereby either one or both of the burners may be operated at will.

A still further object of the invention is to produce a double super-heating pipe coil for the liquid fuel with a back-stop between the coils and the gas outlet pipe to prevent any overflow of the liquid into the gas pipe. By means of this latter feature, the combustion at the burners is always that of gas with no possibility of ungasiied liquids spurting through the burner nipples, which latter condition would result in soot, smoke and carbon deposits.

Another object of the invention is to produce a simple and inexpensive device, and yet one which will be exceedingly effective for the purposes for which it is designed.

'These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claim.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

therein, part of the burner being broken away to show the interior construction thereof.

Fig. 2 is a top plan view of the burner showing one dellecting hood removed and the other partly broken away to show the interior construction of the burners.

Fig. 3 is a sectional view taken on a line X-X of Fig. 2.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the stove. My improved burner comprises a base plate 2 arranged to be placed on the grate bars 3 of the stove. This plate 2 is provided with any desired open spaces 4 so as to permit of the passage of air through the bars 3 and such plate 2 to aid in the combustion of the fuel gas. On the plate 2 are two pairs of supporting legs 5 provided with V-shaped p slots 6 at their upper ends.

The numeral 7 designates supporting legs which are shaped to lit into the slots 6 and which support the base plates 8 of the burners proper. Projecting from the edges of the plates 8 are supporting hooks or grooves 9 arranged to hold the liquid super-heating pipe coils, as will presently appear.

Each plate 8 is provided with an upwardly projecting annular flange 10 and a central orifice 11.

The numeral 12 designates the burner stools which fit between the flanges 10 and each of which is provided with an open pipe 13 which extends through one of the orifices 11. The sides of each stool 12 fit inside of one flange 10, while an annular perforated burner ring 14 lits on the outside of the flange 10, thus forming a space between the stool 12 and this ring 14. The top edge of the ring 14 extends a slight distance above the stool 12 and fitted on the top thereof is the delecting hood 15. The inner surface of this hood 15 is substantially conical in shape, the apex thereof being arranged in a direct line with the pipe 13 and the edges thereof contacting with the top edge of the ring 14. The outer edges of each member l5 flare outwardly, as at 15a.

The fuel inlet pipe 1G projects into the stove 1 and is then formed into a coil 17 which rests in the grooves 9 around one of the plates S. This coil 17 is then connected by a straight pipe 1S which extends across from one burner plate to another and terminates in another coil 19 resting in the grooves 9 adjacent the other plate 8. The..

opposite end of the coil 19 is connected b y a small upright pipe 2O with another pipe 21 normally positioned above the hori- Zonta-l plane of the coils 17 and 19. This pipe 21 is in turn connected bya downwardly extending pipe 22 with the gas outlet pipe 23. This pipe 23 terminates at its ends in the burner valves and nipples 2i and 24a, each having` an independent control stem 25 and 25a, respectively.

Tn practice, a torch 26 is saturated in liquid fuel and suspended by a hook to the pipe 21. This is then lighted and the fuel admitted through the pipe 16 to the coil 17 pipe 18 and coil 19. This fills these pipes and the heat from the torch 26 tends to heat the fuel and also causes the pipe 21 to become very hot. Then as the level ofthe fuel rises into the pipe 20 and gas is generated and passes into the pipe 21, it becomes superheated and highly gasified and passes down through the pipe 22 and pipe 23 to the nip-` ples 24. and 24C where it may be allowed to pass through either or both of said burn-er nipples by means of the control stems 25 and 25g. The gas which may be permitted to escape through either of said nipples then passes through one of the pipes 13 and strikes the corresponding defiecting hood 15 which, of course, is very hot. This breaks the gas up and thoroughly atomizes it and causes it to be thoroughly mixed with the air which is likewise drawn in through the pipe 13. This thoroughly atomized and aerated gas then passes into the space between the members 12 and 14 and out through the perforations in such member 14, which action also tends to further gasify and atomize it.

.As it passes through these orifices, it is ignited and by this time it is so thoroughly atomized and aerated as to cause it to burn a clear blue flame. This flame strikes the flaring sides 15a of the hood 15 which throws the blaze to all parts of the stove and also thoroughly heats the said hood 15.

The back-stopy pipe 21 prevents any overflow of the liquid fuel into the gas pipe 23 and at the same time the gas pressure in such pipe 21 automatically holds back the flow of the liquid fuel in direct proportion to the amount of gas consumed by the burners. This not only prevents the burning of the raw fuel, butat the same time increases the gasifying of the same, all of which enhances the general result aimed at, to-wit, the burning'of a purer gas and the elimination of carbon, soot and smoke. The double coils 17 and 19 subject the liquid fuel to a double heat which, ofcourse, tends to super-heat the same, as is desirable. l

From the foregoing description, it! will readily be seen that I haveproduced such a device as substantially fulfils the objects of the invention as setv forth herein.

While this specification sets forth inl detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus describedmy invention, what T claim as new and useful and desire to Vsecure by Letters Patent is The combination with two hydrocarbon gas burners, of a single fuelpipe leading to a point adjacent said burners, said pipe then being coiled around one burner and then extending to and being coi-led around the other burner, said pipe then extending to a point substantially midway between the burners and being there provided with a pair of branches, each branch extending to a point vbelow one of said burners, and a discharge nipple at the end; ofy each branch.

In testimony whereof- I afiX my signature in presence of two witnesses.
